"Good improvisation communicates harmonic progression melodically. Effective melodies manipulate harmonic content through the use of guide tones and preparatory gravity notes, masterfully woven in systematic tension, release, and transparent harmonic definition."
From the Piazzolla on Video commentary: "The performance by Quintetto Anedda is more precise and controlled than those of Piazzolla but captures perfectly the rhythmic drive of the work which makes it so interesting. The arrangement is respectful of the original but takes full advantage of the staccato, percussive effect of their plectrum created music. These are classically trained musicians and their music has a conservatory feel to it but the jazz roots of Escualo can still be heard. The performance is a good example of the way Piazzolla's music flows easily between the jazz and classical idioms."
